Applcation'led November 1, 1919. Serial No. 2??,115955.

To all who/m, t may concern? Be it known that I, JAMES J. DUFFY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Auxiliary Rail-Supl for Temporary Use. of which the following is a specification. i

My presentinvention relates to supports for the rails oftracks, and more particu-y larly to auxiliary supports intended for temporary use, as while excavating is being carried on beneath the track and until a permanent support is placed therebeneath. The principal obj ects of my invention are,

aid a rail or rails of a track to safely sustain the load and withstand the forces coming thereupon, incident to trains moving thereover, while the usual road bed vor other support of the -track has been temporarily removed froin beneath a portion of the rail or rails; to provide'supports which may be quickly and conveniently placed into and removed from operativel relation to the rail or rails rendering the support particularly `well adapted for use in connection with track sections which are frequently used and where it is highly desirable not to impede traiiic for'any great length of time; and, to provide supports which are portable, simple in construction and assemblage, and relatively low in cost of manufacture, with little if any cost in upkeep, compared with the device or apparatus now in common. use for the purpose set forth. This invention provides supports which may be readilyy transported to thel sections where `use is temporarily desired and without liability ofv shortage of some of the parts because 'of the relatively few parts required, and enables the rails to be temporarily supported at a relatively low cost in4 labor and equipment.

Another obj ect of my invention is to provide a rail support which is of an auxiliary character. in that it aids in supporting the rails which are mainly supported-by vrrnly resting upon the cross ties at each side ofr the section where additional support is .required because of the removal of a portion rpieces ofordinary railroad .rails disposed laterally and at each side of the rail to be supported, and adapted to prevent lateral movement ofsaid first mentioned Vrails with res neet to the track rail, or vice versa.

ther .objects and advantages of the invention will appear -in the following de-y tailed description, taken in 'connection with `the accompanying drawings, forming. a part of the specification, and in which drawings:-

Specification of Letters raten@ rliat'elrgedt 1920. i

Fig. 2A is a -view partly in side elevation and partly in section longitudinally of the railway. u

Fig. 3 is a plan view of the same.l Fig. 4 is an enlarged detailed view partly inelevation showing the support in place in operative relation toanor'dinary track rail.

Fig. 5 is a similar view to Fig. t but showport for the rails C; E an excavation in the. road bed A; and F. sheet piling which may be used to form walls for the excavation.

In the example shown, the road bed A is of thatnature in which 7 designates ordinary earth and 8 ballast of rock, culm or the like, but it is to be vunderstood-that thein- Vvention is applicable to use inyconnection with foundations otherthan`that indicated and that the work beneaththe track orL railway'maybe of a nature other than that requiring excavating, theprincipal object of the invention being to provide a temporary support wherever a portion of the road bed isY removed.

The rails Clare of 'the ordinary construetion, that is, comprising a base 9, web l0 and head 1l, and in the example, shown are secured to cross ties 12 as by spikes 13, it being understood that the bases 9 of the rails rest upon or are in surfacer contact with the upper faces of the ties 12.

.. The auxiliary supportfor each rail comprises a pair of. rails 14 preferably ofthe ordinary railway rail` cross section, that is,

ing one of the elements ofthe support being` each rail comprising a base 15, web 16 and head 17 yand one or more yokes designated generally by 18, the preferred formation of which will be hereinafter more fully set forth. rlhe rails 14 are of such a length as t'o engage upon a number of thejties 12, as shown in Fig. 3 of the drawing, or 1n other words to have considerable surface contact with the ordinary supporting means of the track rails C, and when brought into use are disposed one at each side of the track rails to be supported, and longitudinally thereof.

ln the example shown the yoke 18 is formed of a single piece of metal, such as a bar, of angular cross section and shaped to provide an intermediate portion 19 to engage, in surface contact, the underside of the base 9 of the track rail; and arms 20 extending upwardly from the intermediate portion 19, the end portion of each arm being shaped as indicated at 21 to embrace the head 17 of the rail 14. This is a formation by which the yoke may bear upon the rail 14, and .by embracing the head thereof retain the rail at a fixed distance with respect to the rail C. lt is preferred to dispose the arm 20 extending diagonally and upwardly from the intermediate portion 19, so that the rail 14 will be spaced a sufficient distance from the rail C to provide for wheel flange clearance, and yet form the yoke from a single bar of metal. Tt is also preferred to provide downwardly extending projections 22 on the end portions of the .arm 2O of suficient length and cross section Thus when the yoke is in assembled relation to the rail C and rails 14, all three rails may rest firmly upon the cross ties 12.

The best mode of assemblage T have found in practice to be as follows:

@ne or more of the yokes having been passed se as to dispose the' intermediate portion 19 beneath the track rail, the 4yoke may be canted as shown in Fig. 5 of the drawing so that one of the rails 14 may be moved laterally into place longitudinally of the track rail beneath 'which excavation is to takeV place. The yoke is then moved so that its end portion 21 engages firmly the head 17 of the adjacent rail. This disposes the intermediate portion 19 into firm engagement with the underside of the base 9 of track rail C. A pinch-bar, or other device, not shown in the drawing, may then be used, engaging the projections 22 at the side of the yoke opposite to the rail 14 which has already been assembled into place, and the rail C elevated suiiiciently to permit the other rail 14 to be slipped into place longitudinally of the rail C, beneath the portion 21, after which the rail C, and yoke is permittedto return to a normal position. This may necessitate first releasing the spikes 13 for approximately an eighth of an inch in length, before the rail C is elevated. After the yokes are assembled into place, engaging the rails 14, spikes 25 may be used for the purpose of further seare primarily spaced, and held in spaced relation to the rail C by the preferred configuration of the yokes,'as hereinbefore set forth.

Track supports of the character herein disclosed as the preferred embodiment, have been subjected to test and have been found to effectively aid in supporting the track rail when the ordinary road bed has been removed from beneath a portion of the track, and it is to be observed that in assembling the support in operative relation to the track rail it is not necessary to first excavate a considerable amount of the ballast from between the ties in order to place the yokes in operative relation to the track rail and that, with these yokes primarily disposed in operative relation to the rail, no great length of time is consumed in arranging the rails 14 in operative relationto the yokes. Likewise, when removing the auxiliary support, it is possible to tamp the ballast securely about the ties before removing the auxiliary support, or otherwise re- -place the road bed,for with the auxiliary support in place, the track rail C rests firmly upon the ties throughout its length.

While l have herein described the rails 14 as being of the ordinary cross section of railway rails, it is to be understood that this is with the view of convenience inasmuch as such rails are available and capable of functioning as described, and the yokes 18 may be made of a standard size to fit such rails, as well as the track rail, however, rails of other cross section, functioning as beams, may be used, and other changes in details 'made, without departing from the spirit of my invention; but,
